The novel coronavirus disease ۲۰۱۹ (COVID-۱۹)-related pandemic has been in existence for almost ۲ years now after its possible emergence from a wet market in the city of Wuhan of the Chinese mainland. Evidence of the emergence and transmission of this virus was attributed to bats and pangolins. The causative virus, severe acute respiratory syndrome coronavirus-۲ (SARS-CoV-۲), has rapidly spread globally, affecting humans considerably with its current death toll to be over ۴.۷ million out of more than ۲۳۳ confirmed cases as of September ۲۰۲۱. The virus is constantly mutating and continuously trying to establish itself in humans by increasing its transmissibility and virulence through its numerous emerging variants. Several countries have been facing multiple waves of COVID-۱۹ outbreaks one after the other, putting the medical and healthcare establishments under tremendous stress. Although very few drugs and vaccines have been approved for emergency use, their production capabilities need to meet the needs of a huge global population. Currently, not even a quarter of the world population is vaccinated. The situation in India has worsened during the ongoing second wave with the involvement of virus variants with a rapid and huge surge in COVID-۱۹ cases, where the scarcity of hospital infrastructure, antiviral agents, and oxygen has led to increased deaths. Recently, increased surveillance and monitoring, strengthening of medical facilities, campaigns of awareness programs, progressive vaccination drive, and high collaborative efforts have led to limiting the surge of COVID-۱۹ cases in India to a low level. This review outlines the global status of the pandemic with special reference to the Indian scenario.
